Introduction
STM32 L1 series of ultra-low-power MCUs
ST’s ARM® Cortex®-M3-based STM32L1 series uses ST’s proprietary ultra-low-leakage process technology with an innovative autonomous dynamic voltage scaling and 5 low-power modes offering unprecedented platform flexibility to fit any application. The STM32 L1 series extends the ultra-low-power concept with no compromise on performance.
More than just ultra-low-power MCUs, the STM32L1 series offers a wide portfolio of features, memory sizes and package pin counts.
Combining ultra-low power and performance, the portfolio covers from 32 to 512 Kbytes of Flash memory (with up to80 Kbytes of SDRAM and 16 Kbytes of true embedded EEPROM) and from 48 to 144 pins.
This innovative architecture (voltage scaling, ultra-low-power MSI oscillator) gives your design more performance for a very low power budget. The large number of embedded peripherals, such as USB, LCD interface, op amp, comparators, ADC with fast on/off mode, DAC, capacitive touch and AES, makes the STM32L1 series an expandable platform to fit all your requirements.
The series is available in 4 different lines:
STM32L100 Value line
STM32L151
STM32L152 (LCD)
STM32L162 (LCD and AES-128).
Ultra-low-power mode: 280 nA with backup registers (3 wakeup pins)
Ultra-low-power mode + RTC: 900 nA with backup registers (3 wakeup pins)
Low-power run mode: down to 9 μA
Dynamic run mode: down to 177 μA/MHz

STM32L152D-EVAL – Evaluation board for STM32L1 series – with STM32L152ZD MCU
The STM32L152D-EVAL evaluation board is a complete demonstration and development platform for the STM32 L1 series of ultra-low-power MCUs and includes an STM32L152ZDT6 ARM Cortex-M3 32-bit microcontroller with 384 KB of Flash memory. An ST‐LINK-v2 is integrated on the board as an embedded in-circuit debugger / programmer for the STM32L152ZDT6.
The full range of hardware features on the board helps you develop your own applications and evaluate all peripherals (USB FS, USART, audio DAC, microphone ADC, dot-matrix LCD, LCD glass, IrDA, LDR, SRAM, NOR Flash, MicroSD Card, temperature sensor and so on).
